Why are some of us more prone than others to coronary heart disease?
cricket20 [7]
"Coronary heart disease, North America’s number one cause of death, has been linked with the competitive, hard-driving, impatient, and (especially) anger-prone Type A personality. Under stress, the body of a reactive, hostile person secretes more of the hormones that accelerate the buildup of plaque on the heart’s artery walls. Type B personalities are more relaxed and easygoing. Chronic stress also contributes to persistent inflammation, which heightens the risk of clogged arteries and depression."

OR

Coronary heart disease (CHD) could be the thinning or impediment in the coronary thrombosis veins, normally brought on by coronary artery disease. Coronary artery disease (at times termed “stiffing” or maybe “blocking” in the arterial blood vessels) may be the build-up associated with trans fat and fatty deposits (named plaques) around the intrinsic artery walls.

musickatia [10]

Answer:

C.  Oceans are carbon sinks because they store more carbon than they emit.

Explanation:

Oceans are carbon sinks because they store more carbon than they emit. Most of the carbon is produced in the respiration process as well as burning of fossil fuels. This carbon moves to the atmosphere and dissolved into the ocean which is required by the vegetation of ocean. Due to this carbon, vegetation produced more food for the organisms. About 25% of all CO2 emissions are absorbed by the ocean. Source is the part of a plant where materials are produced e.g. leaves whereas Sink refers to the part of the plant where the substrate can be stored e.g. roots or stem for starch.
